* add example for file on VFAT filesystem usageWaldemar Brodkorb2015-02-17-0/+3
| | | | | | | | For example on a raspberry pi the u-boot environment can be saved in a file on the first VFAT partition. This example illustrates how to use it with fw_printenv/fw_setenv. Signed-off-by: Waldemar Brodkorb <wbx@openadk.org>
* tools/env: Fix environment size and CRC on 64-bit hostsDominic Sacré2014-11-07-1/+1
| | | | | | | | | | | On architectures where 'long' is 64 bit, the u-boot environment as seen by the fw_env tools was missing 4 bytes. This patch fixes getenvsize(), and thus also ensures that the environment's CRC32 checksum is calculated correctly.

* tools/env: change stripping strategy to allow no-strippingThomas Petazzoni2014-09-24-6/+8
| | | | | | | | | | | | | | | | | | | | | When building the U-Boot tools for non-ELF platforms (such as Blackfin FLAT), since commit 79fc0c5f498c3982aa4740c273ab1a9255063d9c ("tools/env: cross-compile fw_printenv without setting HOSTCC"), the build fails because it tries to strip a FLAT binary, which does not make sense. This commit solves this by changing the stripping logic in tools/env/Makefile to be similar to the one in tools/Makefile. This logic continues to apply strip to the final binary, but does not abort the build if it fails, and does the stripping in place on the final binary. This allows the logic to work fine if stripping doesn't work, as it leaves the final binary untouched.

* kconfig: switch to KconfigMasahiro Yamada2014-07-30-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit enables Kconfig. Going forward, we use Kconfig for the board configuration. mkconfig will never be used. Nor will include/config.mk be generated. Kconfig must be adjusted for U-Boot because our situation is a little more complicated than Linux Kernel. We have to generate multiple boot images (Normal, SPL, TPL) from one source tree. Each image needs its own configuration input. Usage: Run "make <board>_defconfig" to do the board configuration. It will create the .config file and additionally spl/.config, tpl/.config if SPL, TPL is enabled, respectively. You can use "make config", "make menuconfig" etc. to create a new .config or modify the existing one. Use "make spl/config", "make spl/menuconfig" etc. for spl/.config and do likewise for tpl/.config file. The generic syntax of configuration targets for SPL, TPL is: <target_image>/<config_command> Here, <target_image> is either 'spl' or 'tpl' <config_command> is 'config', 'menuconfig', 'xconfig', etc. When the configuration is done, run "make". (Or "make <board>_defconfig all" will do the configuration and build in one time.) For futher information of how Kconfig works in U-Boot, please read the comment block of scripts/multiconfig.py. By the way, there is another item worth remarking here: coexistence of Kconfig and board herder files. Prior to Kconfig, we used C headers to define a set of configs. We expect a very long term to migrate from C headers to Kconfig. Two different infractructure must coexist in the interim. In our former configuration scheme, include/autoconf.mk was generated for use in makefiles. It is still generated under include/, spl/include/, tpl/include/ directory for the Normal, SPL, TPL image, respectively.

| * env: Implement support for AES encryption into fw_* toolsMarek Vasut2014-03-21-8/+140
| | | | | | | | | | | | | | | | | | | | | | | | Implement support for encrypting/decrypting the environment block into the tools/env/fw_* tools. The cipher used is AES 128 CBC and the implementation depends solely on components internal to U-Boot. To allow building against the internal AES library, the library did need minor adjustments to not include U-Boot's headers which are not wanted to be included and define missing types.

* | fw_env.c: Switch get_config to use '%ms' in sscanfTom Rini2014-04-17-5/+8
|/ | | | | | | | | | We currently limit ourself to 16 characters for the device name to read the environment from. This is insufficient for /dev/mmcblk0boot1 to work for example. Switch to '%ms' which gives us a dynamically allocated buffer instead. We're short lived enough to not bother free()ing the buffer. Signed-off-by: Tom Rini <trini@ti.com>
* kbuild: rename SRCTREE to srctreeMasahiro Yamada2014-03-12-1/+1
| | | | | | | | | | | | | | | Prior to Kbuild, $(TOPDIR) or $(SRCTREE) was used for pointing to the top of source directory. (No difference between the two.) In Kbuild style, $(srctree) is used for instead. This commit renames SRCTREE to srctree and deletes the defition of SRCTREE. Note that SRCTREE in scripts/kernel-doc, scripts/docproc.c, doc/DocBook/Makefile should be keep. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* fw_env: correct writes to devices with small erase blocksDustin Byford2014-03-12-2/+2
| | | | | | | | | | | | | | | | | Some NOR flash devices have a small erase block size. For example, the Micron N25Q512 can erase in 4K blocks. These devices expose a bug in fw_env.c where flash_write_buf() incorrectly calculates bytes written and attempts to write past the environment sectors. Luckily, a range check prevents any real damage, but this does cause fw_setenv to fail with an error. This change corrects the write length calculation. The bug was introduced with commit 56086921 from 2008 and only affects configurations where the erase block size is smaller than the total environment data size.

* fw_env: calculate default number of env sectorsDustin Byford2014-03-12-7/+9
| | | | | | | | | | | | | | | The assumed number of environment sectors (always 1) leads to an incorrect top_of_range calculation in fw.env.c when a flash device has an erase block size smaller than the environment data size (number of environment sectors > 1). This change updates the default number of environment sectors to at least cover the size of the environment. Also corrected a false statement about the number of sectors column in fw_env.config.

* tools/env: cross-compile fw_printenv without setting HOSTCCMasahiro Yamada2014-02-19-6/+18
| | | | | | | | | | | | | | | fw_printenv is a program which mostly runs on the target Linux. Before switching to Kbuild, we needed to set HOSTCC at the command line like this: make HOSTCC=<your CC cross-compiler> env Going forward we can cross compile it by specifying CROSS_COMPILE: make CROSS_COMPILE=<your cross-compiler prefix> env This looks more natural.
